As already mentioned hereinbefore, the compounds of general formula I according to the invention and the physiologically acceptable salts thereof have valuable pharmacological properties, particularly an inhibitory effect on the enzyme p38 MAP-kinase.

The biological properties of the new compounds may be tested as follows:

The inhibition of the p38 MAP-kinase mediated signal transmission may be demonstrated for example by an enzymatic assay. In this, the amount of a substrate phosphorylated by the kinase is quantified. The test is carried out as follows:

Enzymatic Assay:

The kinase reaction is carried out in the presence of HEPES (20 mM, pH 7), MgCl2 (10 mM), DTT (1 mM) and TWEEN20 (0.01%). First, dimethylsulphoxide or inhibitor (final concentration: 1 μM) dissolved in dimethylsulphoxide are placed in a reaction vessel. Then the activated p38 MAP-kinase (final concentration 1 nM) is added and the mixture is incubated for 4 h at ambient temperature. Then a mixture of substrate (GST-tagged ATF2) and ATP is added and everything is incubated together for a further hour (final concentration ATP: 100 μM; final concentration ATF2: 10 nM).

The concentration of phosphorylated ATF2 is quantified by chemoluminescence-induced light emission. For this, a glutathione donor bead (final concentration: 5 μg/ml) which binds to the gluthathione on the ATF2 and phospho-ATF2 antibodies are added to the reaction mixture (final concentration: 3 nM; this binds the phosphate group added by the kinase reaction) to which a Protein A Acceptor Bead (final concentration: 5 μg/ml) binds. These components are dissolved in a buffer which contains 20 mM HEPES pH 7.0, 200 mM NaCL, 80 mM EDTA as well as 0.3% BSA. This reaction mixture is incubated in the dark for 1 hour at ambient temperature. When these beads come physically close, visible light is emitted which is measured in a photometer at 520-620 nm.

Evaluation:

To determine the inhibitory activity of the compounds according to the invention a calculation is made to determine the percentage by which the kinase activity is inhibited at a fixed inhibitor concentration of 1 μM. The maximum activity is determined by non-inhibited kinase. The minimum activity or nonspecific background activity is determined using a reaction mixture without kinase. The compounds of general formula I according to the invention exhibit inhibitory values of >50%, preferably >90%, for example. Table 2 summarises the degree of inhibition of the enzyme p38 MAP-kinase—as described hereinbefore—of the compounds according to the invention detailed in the section “Preparation of the final compounds”.

Experimental Section

General synthesis

The compounds according to the invention may be obtained using methods of synthesis that are known in principle. Preferably the compounds may be obtained using the methods of preparation according to the invention explained in more detail hereinafter.

Compounds of general formula I may be prepared according to the methods illustrated in Schemes 1 and 2; R¹ to R⁴, X and Y have the meaning as defined hereinbefore and hereinafter, Ar denotes the phenyl ring substituted by R⁵, R⁶ and R⁷, PG¹ is a carboxylic acid protecting group (see the description of protective groups provided below), PG² is a phenol protecting group and LG denotes either a leaving group such as halogen, C₁₋₄-alkyloxy, 2,2,2-trifluoroethoxy, aryloxy, C₁₋₄-alkylsulphonyloxy, trifluoromethylsulphonyloxy, arylsulphonyloxy, nitro, cyano, C₁₋₄-alkylsulphanyl, C₁₋₄-alkylsulphinyl, C₁₋₄-alkylsulphonyl, arylsulphanyl, arylsulphinyl or arylsulphonyl or a B(OH)₂, BF₃K, B(OC₁₋₄-alkyl)₂ or B(OCMe₂CMe₂O) group. The two strategies include the same transformations at the respective functional groups, but in a different order; therefore only the individual transformations for the sequence shown in Scheme 1 will be described.

Synthesis strategy 1 starts from 3-hydroxy-benzoic acid derivatives which are either described in the literature or may be prepared analogously to related structures in a manner that is readily apparent to the skilled man. The first reaction step in synthesis strategy 1 is the conversion of the phenolic OH group into a protected derivative, OPG². Suitable protective groups for the OH group of phenols, the preparation and deprotection thereof are dsc hereinafter and may be used analogously here; thus for example methyl, benzyl, allyl, 4-methoxybenzyl and methylsulphonyl may be used as protective groups. Then the protective group PG¹ of the carboxylic acid functionality is removed, in order to react the free acid with the amine component, Ar—NH₂, in an amide linking reaction. The liberation of carboxylic acids is described hereinafter and may be carried out accordingly. The amide linking is carried out after the conversion of the carboxylic acid group into an activated form thereof such as e.g. an acyl fluoride, chloride, bromide, cyanide, imidazolide (N-acylated), an ester, e.g. 2,2,2-trifluoroethyl ester, vinyl ester, phenyl ester, pentafluorophenyl ester, 4-nitrophenyl ester, succinyl-N-oxy-ester, triazinyl ester or arylotriazol-1-oxy ester, or a thioester such as e.g. methylsulphanylcarbonyl and phenylsulphanylcarbonyl. Mixed anhydrides of carboxylic acid with carbonic acid esters, e.g. derived from isobutyl carbonate, or other leaving groups, such as e.g. dimethylaminocarbonyloxy, pyrrol-1-ylcarbonyloxy, piperidin-1-yl-carbonyloxy, morpho-lin-4-ylcarbonyloxy, trimethylcarbamimidoyloxy, N,N,N′,N′-tetramethyl-uronyl, N,N′-dicyclohexyl-uronyl, diisopropoxy-phosphoryloxy, di-(dimethylamino)phos-phoryloxy and dipyrrolidin-1-yl-phosphoryloxy, are also activated forms of carboxylic acid suitable for coupling with an amine. The above-mentioned activated acyl compounds are preferably prepared in a separate reaction step or in situ, depending on their stability. Thus, for example, the acid chloride may be obtained by treating the carboxylic acid with thionyl chloride, phosphorus oxychloride or oxalyl chloride optionally in the presence of catalytic amounts of N,N-dimethylformamide in dichloromethane, 1,2-dichloroethane, acetonitrile, toluene, benzene, tetrahydrofuran, ether or without a solvent in an excess of chlorinating reagent at temperatures between −20 and 120° C. or the imidazolide may be obtained by reacting the carboxylic acid with carbonyldiimidazole in dichloromethane, tetrahydrofuran, acetonitril or 1,4-dioxane at temperatures between 20 and 120° C. Reagents that are suitable for the in situ activation of carboxylic acids include e.g. N,N′-diisopropyl-carbodiimide, N,N′-dicyclohexylcarbodiimide, N-(3-dimethylamino-propyl)-N′-ethyl-carbodiimide, O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumtetrafluoroborate (TBTU), O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HBTU), n-propylphosphonic anhydride, O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU), (benzo-triazol-1-yloxy)-tris-(dimethylamino)phosphoniumhexafluorophosphate (BOP) or (benzotriazol-1-yloxy)-tripyrrolidin-1-yl-phosphoniumhexafluorophosphate (PyBOP). The amide linking reaction is preferably carried out in a solvent such as for example dichloromethane, 1,2-dichloroethane, toluene, benzene, N,N-dimethylformamide, N,N-dimethylacetamide, N-methyl-pyrrolidinone, tetrahydrofuran, acetonitrile, dimethylsulphoxide or mixtures thereof. Alcohols, e.g. methanol, ethanol or isopropanol, or water may in some cases also be used as the solvent or co-solvent. The reactions are preferably carried out in the presence of a base such as e.g. triethylamine, pyridine, imidazole, diisopropylethylamine or potassium carbonate and optionally an additive, e.g. 4-dimethylaminopyridine or 1-hydroxybenzotriazole, at temperatures between −20 and 120° C., but preferably between 0 and 80° C.

After removal of the phenolic O-protecting group (for method see below) the phenol oxygen is converted by reaction with an electrophil or nucleophil of the N-heteroaromatic group into the corresponding diarylether. In reactions with an electrophilic N-heteroaromatic group (LG=anionic leaving group) the reaction may be carried out in the presence of a transition metal catalyst or with no catalyst. Uncatalysed reactions can be carried out particularly well with N-heteroaromatic compounds which carry fluorine, chlorine, nitro, 2,2,2-trifluoroethoxy, C₁₋₄-alkylsulphonyloxy, trifluoromethylsulphonyloxy, arylsulphonyloxy, C₁₋₄-alkylsulphinyl, C₁₋₄-alkylsulphonyl, arylsulphinyl or arylsulphonyl as LG. For this, the phenol is deprotonated with a base such as e.g. sodium hydride, potassium hydride, KOtBu, NaOtBu, NaOMe, NaOEt, NaOiPr, KF, potassium carbonate, caesium carbonate, pyridine, 4-dimethylaminopyridine, NEt₃ or EtNiPr₂, in a solvent, such as for example tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethane, acetone, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidinone, water, methanol, ethanol, isopropanol, dimethylsulphoxide or mixtures thereof and reacted with the electrophil at temperatures between −20 and 180° C., preferably between 0 and 120° C. The reactions may also be carried out under microwave irradiation in a microwave device. If the electrophilicity of the N-heteroaromatic group is not sufficient for substitution by the phenol component, it may be increased by forming the corresponding N-oxide (→pyridine-N-oxide, pyrimidine-N-oxide) by oxidation of a nitrogen atom which is part of the aromatic ring, in toluene, dichloromethane or 1,2-dichloroethane, for example, with e.g. 3-chloroperoxybenzoic acid (mCPBA), hydrogen peroxide or tert-butylhydroperoxide, optionally in the presence of a transition metal catalyst, e.g. methylrhenium trioxide. After the introduction of the phenol group, the N-oxides can then be converted into the N-deoxygenated heteroaromatic groups by reduction, e.g. with Zn or Fe in acetic acid or with hydrogen in the presence of a transition metal such as Pd/C or Rh/C.

Catalysed reactions are preferably carried out with aza-heteroaromatic compounds which carry iodine, bromine, chlorine, trifluoromethylsulphonyloxy, mesyloxy or tosyloxy as LG. Suitable catalysts are complexes, salts or elemental forms of Cu, Ni, Pd or Fe. Phosphines, e.g. triphenylphosphine, tritolylphosphine, tri-cyclohexylphosphine, tri-tert-butylphosphine, 1,1′-bis(diphenylphosphino)ferrocene, substituted (2-phenylphen-1-yl)-di-tert-butylphosphines or (2-phenylphen-1-yl)-dicyclohexylphosphines, 2.2′-bis(diphenylphosphinyl)-1,1′-binaphthyl, 1,3-diaryl-imidazole or imidazolidinecarbene, 2,2,6,6-tetramethylheptan-3,5-dione, thienyl-2-carboxylate, phosphites, nitriles, e.g. acetonitrile or benzonitrile, or alkenes, e.g. dibenzylideneacetone or allyl, may be used in the complexes. Suitable salt forms are for example fluorides, chlorides, bromides, trifluoromethanesulphonates, trifluoroacetates or acetates. Elemental forms of the transition metals are e.g. palladium on charcoal or nanoparticles of palladium or iron. The reactions are preferably carried out in the presence of a base such as e.g. one of those already mentioned for the uncatalysed variant, preferably with NaOtBu, Cs₂CO₃ or K₃PO₄, in a solvent, such as for example tetrahydrofuran, toluene, benzene, 1,4-dioxane, 1,2-dimethoxyethane, acetonitrile, N,N-dim ethylformamide, N,N-dimethylacetamide or N-methylpyrrolidinone, between 0 and 180° C., preferably between 20 and 120° C.

Coupling of the phenol with boron derivatives of the N-heteroaromatic group is preferably carried out under oxidative conditions with Cu(II) salts, e.g. Cu(OCOCH₃)₂, in the presence of molecular sieve and triethylamine, pyridine or 4-dimethylaminopyridine in dichloromethane, 1,2-dichloroethane, toluene, tetrahydrofuran or benzene at 0 to 120° C. or in the microwave at up to 160° C. The reactions may be carried out by using a co-oxidant, e.g. oxygen or pyridine-N-oxide, also with catalytic amounts of Cu(II). The precursor of the N-heteroaromatic group, R²—Ar^(het) (see Scheme 3), is prepared differently depending on the atom that links the groups Ar^(het) and R². If R² is linked to Ar^(het) via an amino group, the process preferably starts from an Ar^(het) that carries a leaving group LG² in the position that is to be linked, which is nucleophilically substituted by the group R² via the amino group. This reaction may be catalysed by a transition metal, preferably a palladium or copper complex, but is preferably carried out, especially where LG²═F, Cl, NO₂, SOC₁₋₄-alkyl or SO₂C₁₋₄-alkyl, without a catalyst in the presence of a base, e.g. KOtBu, K₂CO₃, Na₂CO₃, Cs₂CO₃, pyridine, 4-dimethylaminopyridine, NEt₃ or EtNiPr₂, in for example tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethan, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, N-methyl-pyrrolidinone, water, methanol, ethanol, isopropanol, dimethylsulphoxide or mixtures thereof at temperatures between 0 and 180° C., preferably between 20 and 120° C. Alternatively the group R² may be attached to the Ar^(het) group by a transition metal, a salt or complex thereof; LG² in this case is Cl, Br, I, OSO₂CF₃, OSO₂Me, OSO₂ToI, for example. Catalysts derived from palladium and copper, e.g. Pd₂(dibenzylideneacetone)₃ combined with (2-dimethylaminophenylphen-1-yl)-di-tert-butyl-phosphine, [2-(2,4,6-triisopropylphenyl)phen-1-yl]dicyclohexyl-phosphine, 2-chloro-1,3-bis(2,6-diisopropylphenyl)-1.3.2-diazaphospholidine or [2-(2,4,6-triisopropylphenyl)phen-1-yl]-di-tert-butyl-phosphine or CuI combined with 2-(isopropylcarbonyl)-cyclohexanone or trans-1,2-di-(methylamino)-cyclohexane, which are preferably used in solvents such as tetrahydrofuran, toluene, benzene, 1,4-dioxane, 1,2-dimethoxyethane, N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidinone or acetonitrile between 0 and 180° C., preferably between 20 and 120° C., are particularly suitable for this purpose.

In cases where R² is attached to Ar^(het) through O, the procedure as described above (see Schemes 1 and 2) may be used for preparing the diarylethers. The hydroxy group may also be introduced in a manner catalysed by transition metals or uncatalysed. The reaction conditions referred to as being suitable may be used analogously here (cf. Also on the subject of O- and N-linking: Angew. Chem. 2003, 115, 5558-5607 and literature cited therein).

In order to prepare an Ar^(het)—R² linked via a C, transition metal-catalysed coupling of a Ar^(het)-LG² to a C-nucleophil of R² is preferably used, wherein LG² denotes Cl, Br, I, OSO₂CF₃, OSO₂Me or OSO₂ToI. Suitable catalysts may be complexes of the transition metal, preferably Pd, Ni, Fe and Cu, with phosphines [e.g. tri-tert-butylphosphine, tricyclohexylphosphine, 2.2′-bis(diphenylphosphinyl)-1,1′-binaphthyl, substituted (2-phenyl-phen-1-yl)-dicyclohexylphosphine (e.g. Xphos), substituted (2-phenyl-phen-1-yl)-di-tert-butylphosphine, triphenylphosphine, tritolylphosphine, trifurylphosphine, 1,1′-bis(diphenylphosphinyl)ferrocene], phosphites, 1,3-disubstituted imidazolecarbenes or imidazolidinecarbenes, dibenzylideneacetone, allyl or nitriles, and elemental forms of the transition metal such as e.g. palladium on charcoal or nanoparticles of Pd or Fe may also be suitable. The active complexes are frequently only prepared in situ from salt forms of the transition metal, using inter alia fluorides, chlorides, bromides, acetates, triflates or trifluoroacetates. The reaction is preferably carried out with a trifluoroborate, a boric acid or a boric acid ester (Suzuki or Suzuki-like coupling), a zinc halide (Negishi or Negishi-like coupling), a stannane (Stille or Stille-like coupling), a silane (Hiyama or Hiyama-like coupling), or a magnesium halide (Kumada or Kumada-like coupling) of the C to be coupled by R². Depending on the nature of the electrophilic and nucleophilic reactant additives such as halides, e.g. LiCl, KF, nBu₄NF, hydroxides, e.g. KOH, K₂CO₃, Cs₂CO₃, silver salts, e.g. Ag₂O or AgOTf, and copper salts, e.g. CuCl, CuI or copper(I)thiophene carboxylate, may be advantageous or even essential. The coupling is optionally carried out in dichloromethane, N,N-dimethylformamide, N-methylpyrrolidinone, benzene, toluene, tetrahydrofuran, water, ethyl acetate, alcohol, ether, dimethylsulphoxide, 1,2-dimethoxyethane, 1,4-dioxane or mixtures thereof, while depending on the nucleophil one or other solvent may be less suitable or even totally unsuitable. The reactions are preferably carried out between −10 and 180° C.

If the group Ar^(het) carries a carboxy or acyl group in the desired position the group R² may also be synthesised through this. Possible links are inter alia through a carboxylic acid amide function, wherein R² is bound to Ar^(het) via an aminocarbonyl group, and an R² linked via an aminomethyl unit. The synthesis of carboxylic acid amides is described hereinbefore and may be used analogously here. The attachment via an aminomethyl unit is preferably produced by reductive amination of the acylated Ar^(het) with a primary or secondary amine. For this, the reactants are reacted in the presence of a reducing agent, e.g. NaBH(OCOCH₃)₃, NaH₃B(CN) or NaBH₄, and optionally a Lewis acid, e.g. Acetic acid or ZnCl₂, in tetrahydrofuran, 1,4-dioxane, methanol, ethanol, isopropanol, water, N,N-dimethylformamide, N-methyl-pyrrolidinone, acetonitrile, toluene, dichloromethane or 1,2-dichloroethane at −10 to 100° C. Alternatively this aminomethyl link may also be obtained by reduction of the above-mentioned carboxylic acid amide function. Suitable reducing agents for this purpose include inter alia lithium aluminium hydride, diisobutylaluminium hydride or borans, which are preferably used in tetrahydrofuran, 1,4-dioxane, ether, toluene or dichloromethane at −50 to 100° C.

Some transformations starting from compounds of general formula I or closely related compounds will now be described by means of which further structures of general formula I may be obtained.

If a compound of general structure I is obtained which contains an aromatic/heteroaromatic amino group, this may be transformed into the corresponding aromatic/heteroaromatic chloride, fluoride, bromide, cyanide, hydroxide, azide, sulphide or thiol by converting the amino group into a diazo group and subsequently reacting the latter with a chloride, fluoride, bromide, cyanide, hydroxide, azide, sulphide or thiol source.

If a compound of general structure I is obtained which contains an amino, alkylamino or dialkylamino fragment, this may be converted into the corresponding alkylamino, dialkylamino or trialkylamino derivative by alkylation with an alkyl elektrophil or by reductive alkylation with an aldehyde or ketone.

If a compound of general structure I is obtained which carries an aromatic/heteroaromatic Cl, Br, I, F₃CO₂SO, MeO₂SO or ToIO₂SO group, this may be converted into the corresponding derivatives by a transition metal-mediated substitution of the above-mentioned groups by aryl, alkenyl, alkynyl or alkyl groups.

If a compound of general structure I is obtained which carries an aromatic/heteroaromatic Cl, Br, I, F₃CO₂SO, MeO₂SO or ToIO₂SO group, this may be converted into the corresponding carboxylic acid esters by a transition metal-mediated substitution of the above-mentioned groups by alkyloxycarbonyl.

If a compound of general structure I is obtained which carries a carboxylic acid ester functionality, this may be transformed by reduction into the corresponding aldehyde.

The subsequent acylation or sulphonylation is optionally carried out in a solvent or mixture of solvents selected from CH₂Cl₂, benzene, chlorobenzene, toluene, tetrahydrofuran or 1,4-dioxane with a corresponding acyl or sulphonylelectrophile, optionally in the presence of a tertiary amine, an inorganic base and/or a dehydrating reagent. Commonly used reagents are for example thionyl chloride, isobutyl chloroformate, trimethylchlorosilane, sulphuric acid, methanesulphonic acid, p-toluenesulphonic acid, PCl₃, P₂O₅, N,N′-dicyclohexylcarbodiimide, N,N′-carbonyldiimidazole, triphenylphosphine with CCl₄ or combinations thereof, which are optionally used in the presence of 4-dimethylaminopyridine and/or 1-hydroxybenzotriazole between 0 and 150° C., preferably between 0 and 80° C.

The subsequent esterification is carried out with the corresponding alcohol, optionally in a solvent or mixture of solvents selected from CH₂Cl₂, N,N-dimethylformamide, benzene, chlorobenzene, toluene, tetrahydrofuran or 1,4-dioxane or particularly preferably in the alcohol itself, with an acid, e.g. hydrochloric acid or sulphuric acid, or a dehydrating reagent. Isobutyl chloroformate, trimethylchlorosilane, sulphuric acid, methanesulphonic acid, thionyl chloride, p-toluenesulphonic acid, N,N′-dicyclohexylcarbodiimide, N,N′-carbonyldiimidazole, PCl₃, P₂O₅, triphenylphosphine/CCl₄ or combinations thereof, optionally in the presence of 4-dimethylaminopyridine and/or 1-hydroxybenzotriazole, are among the reagents frequently used. The reactions are carried out at −20-100° C., preferably at 0-80° C.

The esterification may also be carried out with an alkyl electrophile such as e.g. MeI, Me₂SO₄, BnBr or allylbromide in the presence of a base, e.g. CsOH, Cs₂CO₃, K₂CO₃, NaOH, NEt₃.

The subsequent alkylation/etherification is optionally carried out in e.g. dichloromethane, benzene, toluene, N,N-dimethylformamide, tetrahydrofuran or 1,4-dioxane with an alkylating agent of the corresponding halide or sulphonic acid ester, e.g. MeI, MeBr, EtBr, Me₂SO₄, BnCl, optionally in the presence of a tertiary organic base or an inorganic base at temperatures between 0 and 150° C., preferably between 0 and 100° C.

The subsequent formation of a urea from an amine may be carried out e.g. in a solvent or mixture of solvents selected from dimethylformamide, N-methylpyrrolidinone, toluene, acetonitrile, dichloromethane 1,2-dichloroethane, tetrahydrofuran, ether, 1,2-dimethoxyethane or dioxane with an isocyanate or carbamoyl chloride, optionally in the presence of a tertiary organic base, e.g. NEt₃ or EtNiPr₂, or an inorganic base, e.g. K₂CO₃ or CaO, at 0 to 180° C., preferably at 5 to 120° C. The use of additives such as pyridine or 4-dimethylaminopyridine may be advantageous.

The subsequent reduction of a nitro group is carried out for example with hydrogen in the presence of a transition metal catalyst, e.g. palladium on charcoal, PtO₂ or Raney nickel, or with iron or zinc in the presence of an acid such as acetic acid.

The subsequent cleaving of a C₁₋₄-alkyloxycarbonyl group in order to form the free carboxylic acid is effected for example by acid or basic hydrolysis with HCl, sulphuric acid, LiOH, NaOH or KOH in an aqueous or alcoholic solvent or mixture of solvents.

The subsequent exchange of a carboxy group, e.g. Carboxylic acid or activated carboxylic acid group, for a nitrogen group is carried out e.g. by a breakdown reaction via the corresponding acylazide (e.g. Curtius degradation, Hofmann degradation). The acylazide is obtained e.g. by reacting the carboxylic acid with (PhO)₂P(O)N₃ in the presence of a base, e.g. NEt₃, iPr₂NEt, pyridine, 4-dimethylaminopyridine, K₂CO₃ or Cs₂CO₃, in e.g. cyclohexane, tert-butanol, toluene, benzene, dichloromethane, 1,2-dichloroethane, 1,4-dioxane, tetrahydrofuran, N,N-dimethylformamide or mixtures thereof. Starting from an activated carboxylic acid function, e.g. acyl chloride, mixed anhydrides with e.g. urethanes, carbonic acid esters or phosphoric acid esters, aryl esters such as pentafluorophenyl or 4-nitrophenylesters, alkyl- or arylthioesters, the acylazide may be obtained after reaction with an azide nucleophil, e.g. NaN₃ or Me₃SiN₃, optionally in the presence of an additive, e.g. Bu₄NBr, preferably in toluene, benzene, tetrahydrofuran, ether, 1,4-dioxane, dichloromethane, N,N-dimethylformamide, N-methylpyrrolidinone, acetonitrile, acetone, water or mixtures thereof; depending on the azide source some of the combinations mentioned are unsuitable. The acylazide is rearranged—possibly only as a result of the increase in temperature to preferably 60 to 140° C.—to form the isocyanate, which may be isolated in the case of an inert solvent. The free amine may be obtained therefrom by the addition of water, the corresponding urethane by the addition of alcohol and the corresponding urea after the addition of an amine.

The subsequent conversion of a reactive carboxylic acid functionality into the corresponding carboxylic acid amide is achieved by reaction with the corresponding amine, preferably in a solvent such as dichloromethane, N,N-dimethylformamide, N-methylpyrrolidinone, benzene, toluene, chlorobenzene, tetrahydrofuran, 1,4-dioxane, mixtures thereof or in the amine itself, optionally in the presence of a tertiary organic amine base or an inorganic base and optionally with 4-dimethylaminopyridine as additive, at temperatures of 0 to 180° C., preferably between 0 and 80° C.

The subsequent conversion of an aromatic/heteroaromatic amino group is achieved by diazotisation of the amino group with for example nitric acid, a nitrosonium source or equivalents thereof such as e.g. NaNO₂/HCl, NOBF₄, tert-butylnitrite or isoamylnitrite. The diazotisation is carried out for example in dichloromethane, 1,2-dichloroethane, N,N-dimethylformamide, N-methylpyrrolidinone, benzene, toluene, chlorobenzene, tetrahydrofuran, water, ethyl acetate, alcohol, ether, 1,2-dimethoxyethane, 1,4-dioxane or mixtures thereof at −10 to 100° C. (diazotisations of amino groups are described for example in Angew. Chem. Int. Ed. 1976, 15, 251 and the literature cited therein). The subsequent exchange of the diazo group for a cyano group, a chlorine or bromine atom by means of CuCN, CuCl or CuBr is known in the literature as the Sandmeyer reaction (see March's Advanced Organic Chemistry, Michael B. Smith and Jerry March, John Wiley & Sons Inc., 6. Ed., New Jersey, 2007 and literature cited therein). The reaction is preferably carried out between −10 and 120° C. in one of the above mentioned solvents or mixtures. The exchange of a diazo group for fluorine may be carried out by reacting the diazo compound with an alkali metal tetrafluoroborate or tetrafluoroboric acid at 20 to 160° C.; this reaction is known as the Schiemann reaction. Iodine may be introduced by treating the diazo compound with an iodide, e.g. NaI, preferably in water or an aqueous mixture of solvents, at 0 to 120° C. The diazo-hydroxy exchange may be achieved by reaction in the presence of water at 0 to 180° C. This reaction normally takes place without any further additives, but the addition of copper oxide or strong acid may be advantageous. Mercapto or alkylsulphanyl groups may be introduced by reacting the diazo compound with alkali metal disulphides or dialkylsulphides at temperatures of 0 to 120° C.; depending on the species of sulphur to be introduced, inert or aqueous solvent systems will be more suitable (see e.g. Synth. Commun. 2001, 31, 1857 and references cited therein).

The subsequent reductive alkylation of an amine is carried out with the corresponding carbonyl compound, such as e.g. formaldehyde, acetaldehyde, propionaldehyde, acetone or butyraldehyde, and a complex metal hydride, e.g. NaBH₄, LiBH₄, NaHB(OCOCH₃)₃, NaH₃B(CN), preferably at a pH of 6-7 or with hydrogen, at 1 to 5 bar, in the presence of a transition metal, e.g. Pd/C. The methylation may also be carried out with formic acid or formates as reducing agent at 60 to 120° C.

The subsequent exchange of an aromatic/heteroaromatic chlorine, bromine, iodine atom or an aromatic/heteroaromatic trifluoromethylsulphonyloxy, mesyloxy or tosyloxy group for an aryl, heteroaryl, alkenyl, alkynyl or alkyl group is preferably mediated by a transition metal catalyst, e.g. those derived from Pd, Ni, Rh, Cu and Fe. Suitable catalysts or precursors thereof may be complexes of the transition metals with e.g. phosphines [e.g. tri-tert-butylphosphine, tritolylphosphine, tricyclohexylphosphine, triphenylphosphine, substituted (2-phenyl-phen-1-yl)-dicyclohexylphosphine, trifurylphosphine, substituted (2-phenyl-phen-1-yl)-di-tert-butylphosphine, 1,1′-bis(diphenylphosphino)ferrocene], 1,3-disubstituted imidazolecarbenes, 1,3-disubstituted imidazolidinecarbenes, phosphites, dibenzylideneacetone, allyl or nitriles, elemental forms of the transition metals, e.g. Pd/C or nanoparticles of Pd or Fe, salts of the transition metals, such as e.g. fluoride, chloride, bromide, acetate, trifluoromethanesulphonate or trifluoroacetate, or combinations thereof. The exchange is preferably carried out with the corresponding alkali metal trifluoroborate, boric acid or ester (Suzuki or Suzuki-like reaction), zinc halide (Negishi or Negishi-like reaction), stannan (Stille or Stille-like reaction), silane (Hiyama or Hiyama-like reaction), magnesium halide (Kumada or Kumada-like reaction) of the aryl, alkenyl or alkyl group that is to be introduced. The exchange for a terminal alkyne is preferably carried out with the same or the corresponding zinc acetylide. Depending on the course of the reaction and the nature of the reactants, additives such as e.g. halides, e.g. LiCl, KF, nBu₄NF, hydroxides, e.g. KOH, K₂CO₃, Cs₂CO₃, K₃PO₄, silver salts, e.g. Ag₂O or AgOSO₂CF₃, copper salts, e.g. CuCl or copper(I)thiophenecarboxylate may be advantageous or even essential. CuI is a preferred additive for coupling with terminal alkynes (Sonogashira reaction). The reactions are preferably carried out in dichloromethane, N,N-dimethylformamide, N-methylpyrrolidinone, benzene, toluene, tetrahydrofuran, water, ethyl acetate, alcohol, ether, dimethylsulphoxide, 1,2-dimethoxyethane, 1,4-dioxane or mixtures thereof, the correct choice of solvent being dependent on the nucleophil and some cannot be reacted in all of them. The reactions are preferably carried out at −10 to 180° C.

The subsequent exchange of an aromatic/heteroaromatic chlorine, bromine, iodine atom or an aromatic/heteroaromatic trifluoromethylsulphonyloxy, mesyloxy or tosyloxy group for an alkyloxycarbonyl group is achieved by reacting the compound in question under a CO atmosphere in the presence of the corresponding alcohol and a transition metal catalyst. Suitable catalyst systems are e.g. Pd(OCOCH₃)₂ combined with PPh₃, Pd(OCOCH₃)₂ combined with Ph₂P(CH₂)₃PPh₂, PdCl_(2[)1,1′-bis(diphenylphosphino)ferrocene], (BINAP)PdCl₂, Pd(PtBu₃)₂, PdCl₂(PhCN)₂/Ph₂P(CH₂)₃PPh₂, Pd(OCOCH₃)₂/Ph₂P(CH₂)₄PPh₂, which are preferably used in the presence of bases, such as e.g. KOCOCH₃, NaOCOCH₃, NEt₃, K₂CO₃, NaHCO₃, in solvents, such as e.g. N,N-dimethylformamide, N-methylpyrrolidinone, toluene, 1,4-dioxane or the alcohol itself. The CO pressure is preferably 1 to 5 bar at temperatures between 20 and 160° C.

The subsequent dihydroxylation of an alkenyl group may be carried out with OsO₄ or KMnO₄ as oxidising agent. Preferably OsO₄ and K₂OsO₄ are used in combination with a co-oxidant, e.g. K₃Fe(CN)₆, N-methylmorpholine-N-oxide, NaOCl or NaClO₂, in catalytic amounts. Suitable solvents or ingredients of the solvent include for example water, chloroform, dichloromethane, ether, tetrahydrofuran, acetone, pyridine, acetonitrile, toluene and tert-butanol. Additives such as MeSO₂NH₂, KCl, bases, e.g. K₂CO₃, diazabicyclooctane (DABCO), or ligands, e.g. 1,4-bis(dihydroquinidyl)-phthalazine, which also allow enantioselective dihydroxylation in a uniformly chiral form (see Sharpless dihydroxylation and AD-mix-α, AD-mix-β), are advantageous or even essential. The dihydroxylation may be carried out between −50 and 60° C., but is preferably carried out between −10 and 40° C.

Alternatively this transformation may also be carried out by epoxidation of the double bond, e.g. with 3-chloroperoxybenzoic acid, dimethyldioxiran or H₂O₂ or tBuO₂H combined with a transition metal catalyst, and subsequent opening of the oxiran with a hydroxyl nucleophil, e.g. water, LiOH, NaOH, KOH or NaOOH with subsequent reduction of the O—O— bond.

The subsequent glycol cleaving of a 1,2-dihydroxyethyl fragment is carried out either with Pb(OCOCH₃)₄ or NaIO₄ or HIO₄ as oxidising agent. Pb(OCOCH₃)₄ is used predominantly in aprotic solvents, preferably benzene or dichloromethane, at temperatures between −10 and 80° C. NaIO₄ on the other hand is preferably used in aqueous solvents or mixtures of organic solvents, e.g. dichloromethane, tetrahydrofuran, 1,4-dioxane, methanol, acetonitrile, with water at −10 to 80° C.; NaIO₄ in combination with silica gel or applied to silica gel also enables the reaction to be carried out anhydrously in one of the above-mentioned organic solvents.

The subsequent one-step reduction of a carboxylic acid ester to form the corresponding aldehyde is preferably carried out with diisobutylaluminium hydride (DIBAI-H) in dichloromethane, toluene, hexane, tetrahydrofuran or mixtures thereof at −80 to 20° C. Alternatively a two-step variant is possible comprising reducing the ester to the alcohol, e.g. with DIBAI-H, LiAlH₄ or LiBH₄, and subsequently oxidising the alcohol to form the aldehyde, e.g. with Dess-Martin-Periodinane, pyridine-SO₃ or pyridinium chlorochromate (PCC), in order to achieve this conversion.

In the reactions described hereinbefore, any reactive groups present such as carboxy, carbonyl, hydroxy, amino or alkylamino groups or terminal alkynes may be protected during the reaction by conventional protecting groups which are cleaved again after the reaction (cf. e.g.: Protecting Groups, Philip J. Kocienski, 3^(rd) edition, Georg Thieme Verlag, Stuttgart, 2004 and references cited therein).

For example, a protecting group for a carboxy group may be a trimethylsilyl, methyl, ethyl, tert.butyl, allyl or benzyl group.

For example, a protecting group for a carbonyl group of a ketone or aldehyde may be a ketal or acetal, e.g. derived from methanol, glycol or propane-1,3-diol.

For example, a protecting group for an aliphatic hydroxy group may be the trimethylsilyl, tert-butyldimethylsilyl, triisopropylsilyl, acetyl, pivaloyl, benzoyl, methyl, allyl, benzyl, 4-methoxybenzyl, trityl, methoxymethyl, ethoxymethyl, 2-trimethylsilylethoxymethyl or tetrahydropyranyl group.

Suitable protecting groups for a phenolic OH group, besides those already mentioned for the aliphatic hydroxy group, are methylsulphonyl, tosyl and trifluoromethylsulphonyl.

Suitable protecting groups for an amino or alkylamino group include for example the formyl, acetyl, trifluoroacetyl, ethoxycarbonyl, tert.-butoxycarbonyl, benzyloxycarbonyl, benzyl, 4-methoxybenzyl or 2,4-dimethoxybenzyl group, while additionally phthalyl or tetrachlorophthalyl are also suitable for the NH₂ group.

For example suitable protecting groups for a terminal alkynyl group include the trimethylsilyl, triisopropylsilyl or 2-hydroxyprop-2-yl group.

Any acyl protecting group used is cleaved for example hydrolytically in an aqueous solvent, e.g. in water, isopropanol/water, acetic acid/water, tetrahydrofuran/water or dioxane/water, in the presence of an acid such as trifluoroacetic acid, hydrochloric acid or sulphuric acid or in the presence of an alkali metal base such as lithium hydroxide, sodium hydroxide or potassium hydroxide at temperatures between 0 and 140° C., preferably 10 and 100° C. Another suitable method of cleaving an alkyl ester trifluoroacetyl group is by reaction with iodotrimethylsilane, put in as such or prepared in situ, in an inert solvent such as dichloromethane, 1,2-dichloroethane, toluene or acetonitrile.

Any acetal or ketal protecting group used is preferably cleaved in an aqueous solvent, e.g. in water, isopropanol/water, tetrahydrofuran/water or 1,4-dioxane/water, in the presence of an acid such as acetic acid, trifluoroacetic acid, hydrochloric acid or sulphuric acid, at temperatures between 0 and 120° C., preferably at temperatures between 10 and 100° C.

A trimethylsilyl group is cleaved for example in water, an aqueous solvent mixture or a lower alcohol such as methanol or ethanol in the presence of a base such as lithium hydroxide, sodium hydroxide, potassium carbonate or sodium methoxide. In aqueous or alcoholic solvents, acids such as e.g. hydrochloric acid, trifluoroacetic acid or acetic acid are also suitable. For cleaving in organic solvents, such as for example diethyl ether, tetrahydrofuran or dichloromethane, it is also suitable to use fluoride reagents, such as e.g. tetrabutylammonium fluoride or HF. Besides the use of strong acids, the latter is another suitable method for cleaving larger silyl groups, such as e.g. tert-butyldimethylsilyl and triisopropylsilyl.

A benzyl, methoxybenzyl or benzyloxycarbonyl group is advantageously cleaved hydrogenolytically, e.g. with hydrogen in the presence of a catalyst such as palladium on charcoal, palladium hydroxide or platinum oxide, in a suitable solvent such as methanol, ethanol, ethyl acetate or glacial acetic acid, optionally with the addition of an acid such as hydrochloric acid, at temperatures between 0 and 100° C., but preferably between 20 and 60° C., and under a hydrogen pressure of 1 to 7 bar, preferably 3 to 5 bar. Trimethylsilyl iodide, boron trichloride or boron trifluoride in the presence of a moppin-up reagent, e.g. anisole, thioanisole or pentamethylbenzene, may also be used for cleaving benzylethers including the substituted derivatives thereof. The cleaving of electron-rich benzyl groups, such as e.g. 4-methoxybenzyl, may also be carried out oxidatively with e.g. 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) or cerium ammonium nitrate (CAN), preferably in alcoholic or aqueous solutions, between 10 and 120° C. The 2,4-dimethoxybenzyl group is preferably cleaved in trifluoroacetic acid in the presence of a mopping-up reagent, e.g. anisole.

A tert.butyl or tert.butyloxycarbonyl group is preferably cleaved by treating with an acid such as trifluoroacetic acid or hydrochloric acid, optionally using a solvent such as dichloromethane, 1,4-dioxane, methanol, isopropanol or diethyl ether.

A methyl group on a tertiary amine may be cleaved by treating with 1-chloroethylchloroformate. HBr or BBr₃ are particularly suitable for cleaving methylethers.

Moreover, the compounds of general formula I obtained may be resolved into their enantiomers and/or diastereomers, as mentioned hereinbefore. Thus, for example, cis/trans mixtures may be resolved into their cis and trans isomers, and compounds with at least one optically active carbon atom may be separated into their enantiomers.

Thus, for example, the cis/trans mixtures obtained may be resolved by chromatography into the cis and trans isomers thereof, the compounds of general formula I obtained which occur as racemates may be separated by methods known per se (cf. Allinger N. L. and Eliel E. L. in “Topics in Stereochemistry”, Vol. 6, Wiley Interscience, 1971) into their optical antipodes and compounds of general formula I with at least 2 asymmetric carbon atoms may be resolved into their diastereomers on the basis of their physical-chemical differences using methods known per se, e.g. by chromatography and/or fractional crystallisation, and, if these compounds are obtained in racemic form, they may subsequently be resolved into the enantiomers as mentioned above.

The enantiomers are preferably separated by column separation on chiral phases or by recrystallisation from an optically active solvent or by reacting with an optically active substance which forms salts or derivatives such as e.g. esters or amides with the racemic compound, particularly acids and the activated derivatives or alcohols thereof, and separating the diastereomeric mixture of salts or derivatives thus obtained, e.g. on the basis of their differences in solubility, whilst the free antipodes may be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Optically active acids in common use are e.g. the D- and L-forms of tartaric acid or dibenzoyltartaric acid, di-o-tolyltartaric acid, malic acid, mandelic acid, camphorsulphonic acid, glutamic acid, aspartic acid or quinic acid. An optically active alcohol may be for example (+) or (−)-menthol and an optically active acyl group in amides, for example, may be a (+)- or (−)-menthyloxycarbonyl.

Furthermore, the compounds of formula I may be converted into the salts thereof, particularly for pharmaceutical use into the physiologically acceptable salts with inorganic or organic acids. Acids which may be used for this purpose include for example hydrochloric acid, hydrobromic acid, sulphuric acid, methanesulphonic acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid.

The compounds of general formulae II and III used as starting materials are known from the literature in some cases or may be prepared using methods known from the literature and analogously to the methods described in the Examples, optionally with the additional introduction of protecting groups.
